Study Characteristics

Study Participants

Parents eligible to participate in the study (1) were the primary caretakers of children younger than 5 years of age, (2) spoke English as their first language, and (3) had an intellectual disability. A total of 63 parents from 57 families were recruited; of these, 45 parents from 40 families completed the project. The authors categorized the sample as follows: 82 percent of the parents were from an English-speaking background, 13 percent were from a culturally and linguistically diverse background, and 5 percent were Aboriginal or Torres Strait Islanders.

Home Visiting Services

The authors called this adaptation of SafeCare the Home Learning Project (HLP). The HLP was adapted from the UCLA Parent-Child Health and Wellness Project for the Australian context (e.g., language was changed to reflect Australian usage). The goal of the intervention was to equip parents of young children with the knowledge and skills necessary for managing home dangers, accidents, and childhood illnesses. The HLP consisted of 10 lessons, delivered by a trained parent educator in a one-on-one situation in the parent's home. The lessons lasted 60 to 90 minutes and occurred over a 10- to 12-week period.

Comparison Condition

The research design permitted all parents to receive the HLP in a staggered sequence. Initially, each parent was randomly allocated to one of three groups. However, a fourth group was created of parents who were referred late and would not have been able to complete the staggered sequence. During the first intervention phase, Group 1 (n = 20) received the full HLP intervention. Group 2 (n = 11) received home visits but no parent education. Groups 3 and 4 (n = 10 and n = 4, respectively) received business-as-usual services in this phase. Assessment 2 occurred after the first intervention phase. During the second intervention phase, Group 2 received HLP, Group 3 received lesson booklets only, and Group 4 received HLP. Assessment 3 occurs after this phase. At this point, all groups had received some portion of the intervention.

Staff Characteristics and Training

The HLP adaptation of SafeCare was conducted by trained parent educators.
